Responsibilities
We are looking for a hands-on software and cloud engineer with a strong backend focus who wants to grow within IoT and cloud-native systems.
You will contribute to building scalable IoT and cloud platforms at OBI Smart Technologies Poland, working on systems handling device communication, telemetry ingestion, and automation workflows. You collaborate closely with backend engineers, architects and product teams to deliver reliable and production-ready solutions across AWS-based environments.
Your key responsibilities include:
• Develop and maintain backend services using TypeScript, Node.js, NestJS and Fastify.
• Design and implement REST APIs using OpenAPI standards and validation patterns.
• Contribute to AWS-based IoT and event-processing architectures including IoT Core, MQTT and telemetry ingestion.
• Support development of data processing and automation workflows using Lambda, SQS, Kinesis and Timestream.
• Work with PostgreSQL or Aurora databases and maintain persistence layers using TypeORM.
• Contribute to infrastructure and deployment processes using Terraform or OpenTofu, Docker and CI/CD pipelines.
• Support monitoring, testing, observability and operational stability while occasionally contributing to frontend components in Vue 3.
Benefits
•

You can choose medical care package, meal tickets, sports cards (we have Multisport and on preferential terms, we have membership cards to one of the most popular Gyms), cinema tickets, shop vouchers, discounts and many more.
•
Language Courses – you'll have access to a multi-language learning platform enabling you to practice your language skills and learn new ones!
• Regular and systematic further training opportunities - both internally and from external providers. We support your ongoing learning and development.
• Cooperation within an internal community is our everyday reality. We have networking events, coding challenges, and company parties for different occasions.
Qualifications
• Completed university degree in Computer Science or a comparable technical field.
• 3+ years of experience in backend development using TypeScript and Node.js.
• Good knowledge of REST API design and frameworks such as NestJS.
• Hands-on experience with AWS services such as Lambda, S3, SQS or IoT Core.
• Experience working with relational databases such as PostgreSQL and ORM tools.
• Basic experience with containerization, CI/CD pipelines and infrastructure as code tools.
• Understanding of cloud-native or event-driven architectures
•
Fluent communication skills in English and Polish and availability to work in a hybrid mode with 1–2 office visits per week.
